Filed: 1989-02-06
Abstract: PURPOSE:To make it possible to decrease a gate threshold voltage while improving programming performance by providing, in a semiconductor substrate, source and drain regions of the opposite conductivity type to that of the substrate while constructing these regions into a double structure consisting of a lowly doped conducting layer and a highly doped conducting layer. CONSTITUTION:An element isolating film 2 is formed on a semiconductor substrate 1 of p-type conductivity, for example. A gate 3 is formed on the substrate, and conducting layers 4 and 5 of the opposite conductivity type to that of the substrate 1, namely n<+>type conducting layer 4 and a n<->type conducting layer 5 are formed in source and drain regions in the semiconductor substrate 1. The n<+>type conducting layer 4 may be formed by implanting arsenic ions As<+>, for example, into the substrate 1, while the n<->type conducting layer 5 may be formed by implanting phosphorus ions P<+>, for example, into the substrate 1. In this manner, the source and drain regions have a double diffused structure. Accordingly, an effective channel length is decreased whereby electrons are accelerated more by the short channel effect and the efficiency of generating hot electrons can be improved. Consequently, it is possible to decrease a gate threshold voltage while improving programming performance.

Title: Rear focus type zoom lens
Inventor: ITO YOSHIAKI
IPC: G02B15/20
Filed: 1989-02-07
Abstract: PURPOSE:To reduce aberration variation at the time of focusing by setting the refracting power of four lens groups, the movement conditions of the respective lens groups in power variation, a zoom ratio, the refracting power of the whole system at the wide-angle end and telephoto end, etc., and moving the 3rd group to the object side for the focusing. CONSTITUTION:The zoom lens consists of the 1st group I with positive refracting power, 2nd group II with negative refracting power, 3rd group III with positive refracting power, and high group IV with negative refracting power. Figures (A) and (C) show the positions of the respective lens groups when the zoom lens is put in focus on an infinite-distance body at the wide-angle end and telephoto end and figures (D) and (F) show the positions of the respective lens groups when the zoom lens is put in focus on a short-distance body at the wide-angle end and telephoto end. When the power is varied from the wide-angle end to the telephoto end, the four lens groups are all moved as shown by arrows in the figures (A) and (C). Then when focusing from the infinite-distance body to the short-distance body is performed, the 3rd group is moved to the body side as shown in the figures (D) and (F). Consequently, the aberration variation at the time of focusing is made small and the lens system is reduced in the size on the whole.
